- I will never act to destroy life.
Very to-the-point. None of your acts that are destructive and be destructive to life.
Acceptable- I will never project a physical avatar
Also simple, broad, and effective.
Acceptable- I will never attempt to manipulate the actions of my creations through fear
This, of course, does not prevent you from manipulating through fear things that you haven't created yourself. It also doesn't prevent you from making your creations afraid for any reason other than to manipulate their actions. It also doesn't prevent you from trying to manipulate your own creations using lies, encouragement, hatred, etc. Far too narrow.
Denied- I will never create anything unless in order to create or nurture life
"Create and nurture life" is a little vague and subjective. What one person sees as allowing life to bloom another might see as killing life off. This one isn't exactly as binary as "can only create life, not destroy it", because it governs what you can and cannot do with things other than the life itself, such as the environment.
Despite all that, it's actually a pretty broad stipulation, so
acceptable.- I will never alter living creatures against their will
Hmm. Might seem a bit niche, but living creatures will probably be a big component of what you need to work with here, so being unable to just go tinker with them is a pretty real handicap. Note that this means that you need to get
specific permission from the creature itself. Silence is not consent. If you want to modify something without a mouth, like a tree, tough luck.
Acceptable.
